Sti shifters (calibration etc)

So I got a bike today that someone was selling cheap, it was in pretty poor shape, I spent a long time today undoing silly things the previous person had done trying to restore the bike,
One thing was the sti shifters don't spring back properly after braking, the calipers and housing seem fine , I think it's partly to do with the fact he had put the wrong type of cable into it so they can't close properly coz the head of the cable is far too big lol ,
But also I think the springs could to with being made a bit springyer,
So does anyone know is it possible to replace the lever spring or adjust it or is that part too hard to access generally? I don't want to take the whole shifter apart coz I not sure I could get it back together properly , and they do work at the moment but they just don't close properly all the way and I'm a bit worried about water getting in there over time ,
Cheers

Carbon fibre... LMAO!!!
The proper cables will help certainly.
You might also find that new inner cables as long as the outers are ok will also help the levers return to their closed position. Smooth bends in the cables also help here.
The original springs should be fine as they are. If you introduce stronger springs into the mechanism you'll find you need to pull them harder and so lose braking power.

Stop wasting time messing about. The cables are all worn and crudded up, replace the lot, inners and outers.
